Does more volume mean deeper claims for Hanwit?

Each dot is one of Hanwit’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Hanwit’s own 9.6 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hanwit's grants concentrate

Hanwit Precision Industries Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 71.9% of grants classified under F16B (Devices FOR Fastening OR Securing Constructional Elements OR Machine Parts Together, e.g. Nails, Bolts, Circlips, Clamps, Clips OR WEDGES; Joints OR Jointing). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2016. By volume, Hanwit sits between GrafTech International Holdings Inc. and Haldex Brake Products AB.

Hanwit's three-year grant acceleration

Hanwit Precision Industries Ltd. shows 7 grants in 2022–2024 against only 10 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
